Page Rules are a powerful tool in the vCDN system that allows you to customize how the CDN handles requests to your website based on predefined rules. With Page Rules, you can apply specific settings to one or more URLs, helping to optimize performance, enhance security, or improve user experience.

After you select Create Page Rule, the screen displays as follows:

URL Pattern: enter the URL pattern to apply Page Rule, vCDN supports the declaration type “*” representing a string of multiple characters. For example: /trang_landing_cu.html
